Uranium deposits and signifi cant occurrences are reported from ten regions of Asian Russia. Th ey include all signifi cant districts and present production centers in Russia (>Fig. 10.1).OECD-NEA/IAEA (2005) reports a total of 172 400 t U as remaining resources recoverable at <$80 per kg U, 131 750 t U of which are attributed to the RAR and 40 650 t U to the EAR-I category. Resources distribution by types of deposits amounts to 117 120 t U in volcanic-, 21 410 t U in sandstone-, and 33 870 t in vein-type deposits.
This paper address the question of why giant gold deposits are so unevenly spread over the continents, what processes control their distribution, and how more might be found? Using the source-migration-trap paradigm, it is proposed that the regional distribution of gold deposits is controlled by fluid access to gold sources on a regional scale, and by large-scale migration mechanisms.
The Elatsite porphyry copper deposit is one of the two operating large Bulgarian copper and gold deposits. It is located in the Elatsite-Chelopech ore field, the northernmost part of the Panagyurishte ore district of the Apuseni-Banat-Timok-Srednogorie magmatic and metallogenic belt. The ore mineralization is associated with the Late Cretaceous magmatic activity manifested in the area. It is of vein-disseminated type and builds up a large ore stockwork.
All information about the Earth’s interior comes from field observations and measurements made within the top few kilometers of the surface, from laboratory experiments and from the powers of human deduction, relying on complex numerical modeling. Solid Earth Geophysics encompasses all these endeavors and aspires to define and quantify the internal structure and processes of the Earth in terms of the principles of physics, corresponding mathematical formulations and computational procedures.

The geologic history of the San Manuel-Kalamazoo deposit has provided an opportunity for the examination of vertical and horizontal zoning relationships in a porphyry copper system. Precambrian Oracle "granite," a Laramide monzonite porphyry, and a Laramide dacite porphyry are hosts to zones of potassic, phyllic, argillic, and propylitic assemblages shown to be coaxially arranged outward from a potassic core through phyllic, argillic, and propylitic zones. Alteration zones at depth comprise an outer chlorite-sericite-epidote-magnetite assemblage yielding to an inner zone of quartz-K4eldspar-sericite-chlorite. Mineralization zones are conformable to the alteration zones, the ore zone (with a 0.5% Cu cutoff) overlapping the potassic and phyllic zones.
